100x this. I've unfortunately never been in a position where I had someone to work under to be mentored (being self taught from the age of 12, 32 now), I've found by far my most important skill is critical thinking.

I'm definitely not the fastest learner and am absolutely stunted in some areas (computer science) but through persistence and critical thinking I've been able to excel in any position I've found myself in.

I've also been able to act as a mentor of sorts for several other developers (all but a couple my senior in age) success always comes through their own drive to learn. While my guidance just fills in gaps and helps them through difficult concepts that I personally wasted tons of time struggling through since I didn't have someone point out the clear path for me.

Yes. This is why it’s good to seek out alternative opinions. Having a network of advisers can be very helpful.

This person wasn't asking for opinions on mentors.
